Lansdowne's own community history describes the area's development on former plantation land beside the Potomac River. Virginia's Department of Historic Resources records a different layer of that past at Belmont, where a Federal style manor house was built between 1799 and 1802 and later stood vacant under corporate ownership before its grounds became a country club in the 1990s. Lansdowne's newer sections were built around golf courses and river access, so a lower level near the water and a room near that older house face different conditions.
For a home in River Creek or Lansdowne on the Potomac, describe the lower level's relationship to the river, including elevation, past flooding and any sump or drainage system. Near Belmont Country Club, identify whether the residence is a newer build close to the historic manor grounds or a golf course lot, and note any irrigation feature nearby. In The Village at Leesburg, a unit may share a roof, wall or mechanical room with a business or neighboring residence; describe that layout. Coton Commons homes should come with details of crawlspace access and any addition made since construction.
Local background: Lansdowne on the Potomac HOA: our community, Virginia DHR: Belmont.
01
Grading and drainage were reshaped when golf-course homes were built around the older Belmont house. Describe how your lot's grading directs water, whether a nearby fairway or pond sits close to the foundation, and when your section of the community was completed if that is known.
02
A lower level that opens toward the Potomac has more exposed wall and door area than a fully below-grade room. Describe the distance to the water, any past flooding or high-water mark, and whether a sump system already manages groundwater.
03
A residential unit built above or beside retail space may share a roof, mechanical room or plumbing chase with the business next to it. Identify what borders your unit on each side and describe any odor or stain along a shared wall.
Where we test in Lansdowne, and what to tell us
Lansdowne on the Potomac and River Creek
Homes here sit near the Potomac River and a golf course. Describe the lower level's elevation relative to the yard, any history of water entering the space, and whether a sump pump or perimeter drain is already in place.
Belmont Country Club
New construction here surrounds a much older manor house on the same grounds. For a residence near the golf course, note irrigation lines and drainage close to the foundation, and describe the home's completion date if known.
The Village at Leesburg and Coton Commons
The Village at Leesburg mixes residential units with retail and shared building systems; describe that layout. In Coton Commons, identify crawlspace access and any addition or finished room added after the original construction.
We do not remove mold, so we have nothing to gain from your results. If your report shows a problem, you choose who fixes it. Once the work is done, we can test again and tell you what we find.
Virginia's residential disclosure statement advises buyers to exercise due diligence, including considering a mold assessment conducted by a business following EPA guidance. Confirm the scope and timing with your agent before settlement. A laboratory sample documents a selected place and time; it does not certify an entire home as mold-free or replace advice about your transaction.
Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.
Walk & Talk is a consultation without laboratory samples, useful when you want an evaluation of the property without a defined concern yet. Mold Basic tests one targeted area if you already suspect a specific room. Describe what prompted your question, and the office can help decide which visit fits.
Yes. Describe which walls, floors or ceilings are shared with a neighboring unit or a ground floor business, and whether you have access to those adjoining spaces. The visit addresses your unit's accessible areas; a concern that appears to originate next door may need cooperation from that owner or the building manager.
Proximity to a golf course does not by itself predict conditions inside a house. Irrigation timing, grading and gutter discharge near your specific foundation matter more. Describe any irrigation head, low spot or drainage pattern close to the house, and the technician will assess the accessible property rather than the surrounding landscape.
Note the elevation of that level relative to the yard and the river, and describe any past water entry, sump pump operation or musty odor. Mention whether the space is finished, and how long ago any flooring or drywall was installed, since newer finishes can limit what is visible during the visit.
